BACKGROUND OF THE INVENTION

The present invention relates to apparel finishing and, morespecifically, the use of a laser in the finishing of garments,especially denim including jeans, shirts, shorts, jackets, vests, andskirts, to obtain a faded, distressed, washed, or worn finish orappearance.

In 1853, during the California Gold Rush, Levi Strauss, a 24-year-oldGerman immigrant, left New York for San Francisco with a small supply ofdry goods with the intention of opening a branch of his brother's NewYork dry goods business. Shortly after arriving in San Francisco, Mr.Strauss realized that the miners and prospectors (called the “fortyniners”) needed pants strong enough to last through the hard workconditions they endured. So, Mr. Strauss developed the now familiarjeans which he sold to the miners. The company he founded, Levi Strauss& Co., still sells jeans and is the most widely known jeans brand in theworld. Levi's is a trademark of Levi Strauss & Co. or LS&Co.

Though jeans at the time of the Gold Rush were used as work clothes,jeans have evolved to be fashionably worn everyday by men and women,showing up on billboards, television commercials, and fashion runways.Fashion is one of the largest consumer industries in the U.S. and aroundthe world. Jeans and related apparel are a significant segment of theindustry.

As fashion, people are concerned with the appearance of their jeans.Many people desire a faded or worn blue jeans look. In the past, jeansbecame faded or distressed through normal wash and wear. The apparelindustry recognized people's desire for the worn blue jeans look andbegan producing jeans and apparel with a variety of finishing patterns.The finishing patterns have become part of the jeans style and fashion.Some examples of finishing patterns include combs or honeycombs,whiskers, stacks, and train tracks.

Despite the widespread success jeans have enjoyed, the process toproduce modern jeans with finishing patterns takes processing time, hasrelatively high processing cost, and is resource intensive. A typicalprocess to produce jeans uses significant amounts of water, chemicals(e.g., bleaching or oxidizing agents), ozone, enzymes, and pumice stone.For example, it may take about twenty to sixty liters of water to finisheach pair of jeans.

Therefore, there is a need for an improved process for finishing jeansthat reduces environmental impact, processing time, and processingcosts, while maintaining the look and style of traditional finishingtechniques. There is a need for tool to creating and previewing patternson jeans before laser finishing.

BRIEF SUMMARY OF THE INVENTION

A tool allows a user to create new designs for apparel and preview thesedesigns before manufacture. Software and lasers are used in finishingapparel to produce a desired finishing pattern or other design. Based ona laser input file with a pattern, a laser will burn the pattern ontoapparel. With the tool, the user will be able to create, make changes,and view images of a design, in real time, before burning by a laser.Input to the tool includes fabric template images, laser input files,and damage input. The tool allows adding of tinting and adjusting ofintensity and bright point. The user can also move, rotate, scale, andwarp the image input.

In an implementation, a method for surface projection in an appareldesign system includes providing a garment previewing tool that allowspreviewing on a computer screen of a garment base customized by a userwith a finishing pattern, where the garment previewing tool includes:providing an option for the user to select the garment base and upon theuser's selection, showing a first garment preview image on the computerscreen including a jeans base image for the selected garment base,providing an option for the user to select a finishing pattern from amenu of finishing patterns, where each finishing pattern is associatedwith a laser input file to be used by a laser to produce that finishingpattern onto a jeans garment, after the finishing pattern is selected,showing a second garment preview image on the computer screen includingthe selected finishing pattern in combination with the jeans base image,where the second garment preview image replaces the first garmentpreview image, in the second garment preview image, allowing the user toselect the finishing pattern and modify a sizing of the finishingpattern relative to the jeans base image, where as the user makeschanges, the modified sizing of the finishing pattern is displayed tothe user in response to selecting the finishing pattern, in the secondgarment preview image, allowing the user to select the finishing patternand modify a position of the finishing pattern relative to the jeansbase image, where as the user makes changes, the modified positioning ofthe finishing pattern is displayed to the user in response to modifyingthe position of the finishing pattern, and showing a third garmentpreview image on the computer screen including the jeans base image andselected finishing pattern, with modified sizing or modifiedpositioning, or a combination. The method includes applying a distortionto the third garment preview image, where the distortion approximateshow the jeans base image and selected finishing pattern, with modifiedsizing or modified positioning, or a combination, needs to be modifiedto appear on a three-dimensional mannequin. The method includesprojecting, using a light projector, onto the three-dimensionalmannequin the distorted garment preview image and receiving a firstcaptured image of the distorted garment preview image as projected ontothe three-dimensional mannequin. The method includes refining, based onthe first captured image, the distorted garment preview image. Themethod includes providing a target garment corresponding to the garmentbase selected by the user; and based on a laser input file associatedwith a selected finishing pattern with modified sizing or modifiedpositioning, or a combination, using a laser to create a finishingpattern on an outer surface of the target garment.

The method may include calibration techniques. The method includesbefore projecting, using a structured light technique to determinecontours of the three-dimensional mannequin.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a process flow 101 for manufacturing apparel such as jeans,where garments are finished using a laser. The fabric or material forvarious apparel including jeans is made from natural or synthetic fibers106, or a combination of these. A fabric mill takes fibers and processes109 these fibers to produce a laser-sensitive finished fabric 112, whichhas enhanced response characteristics for laser finishing.

Some examples of natural fibers include cotton, flax, hemp, sisal, jute,kenaf, and coconut; fibers from animal sources include silk, wool,cashmere, and mohair. Some examples of synthetic fibers includepolyester, nylon, spandex or elastane, and other polymers. Some examplesof semisynthetic fibers include rayon, viscose, modal, and lyocell,which are made from a regenerated cellulose fiber. A fabric can be anatural fiber alone (e.g., cotton), a synthetic fiber alone (e.g.,polyester alone), a blend of natural and synthetic fibers (e.g., cottonand polyester blend, or cotton and spandex), or a blend of natural andsemisynthetic fibers, or any combination of these or other fibers.

For jeans, the fabric is typically a denim, which is a sturdy cottonwarp-faced textile in which a weft passes under two or more warpthreads. This twill weaving produces a diagonal ribbing. The yarns(e.g., warp yarns) are dyed using an indigo or blue dye, which ischaracteristic of blue jeans.

Although this patent describes the apparel processing and finishing withrespect to jeans, the invention is not limited jeans or denim products,such as shirts, shorts, jackets, vests, and skirts. The techniques andapproaches described are applicable to other apparel and products,including non-denim products and products made from knit materials. Someexamples include T-shirts, sweaters, coats, sweatshirts (e.g., hoodies),casual wear, athletic wear, outerwear, dresses, evening wear, sleepwear,loungewear, underwear, socks, bags, backpacks, uniforms, umbrellas,swimwear, bed sheets, scarves, and many others.

A manufacturer creates a design 115 (design I) of its product. Thedesign can be for a particular type of clothing or garment (e.g., men'sor women's jean, or jacket), sizing of the garment (e.g., small, medium,or large, or waist size and inseam length), or other design feature. Thedesign can be specified by a pattern or cut used to form pieces of thepattern. A fabric is selected and patterned and cut 118 based on thedesign. The pattern pieces are assembled together 121 into the garment,typically by sewing, but can be joined together using other techniques(e.g., rivets, buttons, zipper, hoop and loop, adhesives, or othertechniques and structures to join fabrics and materials together).

Some garments can be complete after assembly and ready for sale.However, other garments are unfinished 122 and have additional finishing124, which includes laser finishing. The finishing may include tinting,washing, softening, and fixing. For distressed denim products, thefinishing can include using a laser to produce a finishing patternaccording to a design 127 (design II). Some additional details of laserfinishing are described in U.S. patent application 62/377,447, filedAug. 19, 2016, and Ser. No. 15/682,507, filed Aug. 21, 2017, issued asU.S. Pat. No. 10,051,905 on Aug. 21, 2018, which are incorporated byreference along with all other references cited in this application.U.S. patent applications 62/636,108, filed Feb. 27, 2018, and62/715,788, filed Aug. 7, 2018, describe some specific implementationsof a brief builder application and are incorporated by reference.

U.S. patent application Ser. Nos. 16/288,035, 16/288,036, 16/288,038,16/288,042, 16/288,046, 16/288,048, 16/288,050, 16/288,053, and16/288,054, filed Feb. 27, 2019, are incorporated by reference.

Design 127 is for postassembly aspects of a garment while design 115 isfor preassembly aspects of a garment. After finishing, a finishedproduct 130 (e.g., a pair of jeans) is complete and ready for sale. Thefinished product is inventoried and distributed 133, delivered to stores136, and sold to consumers or customers 139. The consumer can buy andwear worn blue jeans without having to wear out the jeans themselves,which usually takes significant time and effort.

Traditionally, to produce distressed denim products, finishingtechniques include dry abrasion, wet processing, oxidation, or othertechniques, or combinations of these, to accelerate wear of the materialin order to produce a desired finishing pattern. Dry abrasion caninclude sandblasting or using sandpaper. For example, some portions orlocalized areas of the fabric are sanded to abrade the fabric surface.Wet processing can include washing in water, washing with oxidizers(e.g., bleach, peroxide, ozone, or potassium permanganate), sprayingwith oxidizers, washing with abrasives (e.g., pumice, stone, or grit).

These traditional finishing approaches take time, incur expense, andimpact the environment by utilizing resources and producing waste. It isdesirable to reduce water and chemical usage, which can includeeliminating the use agents such as potassium permanganate and pumice. Analternative to these traditional finishing approaches is laserfinishing.

FIG. 2 shows a finishing technique that includes the use of a laser 207.A laser is a device that emits light through a process of opticalamplification based on the stimulated emission of electromagneticradiation. Lasers are used for bar code scanning, medical proceduressuch as corrective eye surgery, and industrial applications such aswelding. A particular type of laser for finishing apparel is a carbondioxide laser, which emits a beam of infrared radiation.

The laser is controlled by an input file 210 and control software 213 toemit a laser beam onto fabric at a particular position or location at aspecific power level for a specific amount of time. Further, the powerof the laser beam can be varied according to a waveform such as a pulsewave with a particular frequency, period, pulse width, or othercharacteristic. Some aspects of the laser that can be controlled includethe duty cycle, frequency, marking or burning speed, and otherparameters.

The duty cycle is a percentage of laser emission time. Some examples ofduty cycle percentages include 40, 45, 50, 55, 60, 80, and 100 percent.The frequency is the laser pulse frequency. A low frequency might be,for example, 5 kilohertz, while a high frequency might be, for example,25 kilohertz. Generally, lower frequencies will have higher surfacepenetration than high frequencies, which has less surface penetration.

The laser acts like a printer and “prints,” “marks,” or “burns” afinishing pattern (specified by input file 210) onto the garment. Thefabric that is exposed to the laser beam (e.g., infrared beam) changescolor, lightening the fabric at a specified position by a certain amountbased on the laser power, time of exposure, and waveform used. The lasercontinues from position to position until the finishing pattern iscompletely printed on the garment.

In a specific implementation, the laser has a resolution of about 34dots per inch (dpi), which on the garment is about 0.7 millimeters perpixel. The technique described in this patent is not dependent on thelaser's resolution, and will work with lasers have more or lessresolution than 34 dots per inch. For example, the laser can have aresolution of 10, 15, 20, 25, 30, 40, 50, 60, 72, 80, 96, 100, 120, 150,200, 300, or 600 dots per inch, or more or less than any of these orother values. Typically, the greater the resolution, the finer thefeatures that can be printed on the garment in a single pass. By usingmultiple passes (e.g., 2, 3, 4, 5, or more passes) with the laser, theeffective resolution can be increased. In an implementation, multiplelaser passes are used.

Jeans are dyed using an indigo dye, which results in a blue coloredfabric. The blue color is caused by chromophores trapped in the fabricwhich reflect light as a blue color. U.S. patent application 62/433,739,filed Dec. 13, 2016, which is incorporated by reference, describes adenim material with enhanced response characteristics to laserfinishing. Using a denim material made from indigo ring-dyed yarn,variations in highs and lows in indigo color shading is achieved byusing a laser.

FIG. 3 shows a weave pattern of a denim fabric 326. A loom does theweaving. In weaving, warp is the lengthwise or longitudinal yarn orthread in a roll, while weft or woof is the transverse thread. The weftyarn is drawn through the warp yarns to create the fabric. In FIG. 3 ,the warps extend in a first direction 335 (e.g., north and south) whilethe wefts extend in a direction 337 (e.g., east and west). The wefts areshown as a continuous yarn that zigzags across the wefts (e.g., carriedacross by a shuttle or a rapier of the loom). Alternatively, the weftscould be separate yarns. In some specific implementations, the warp yarnhas a different weight or thickness than the weft yarns. For example,warp yarns can be coarser than the weft yarns.

For denim, dyed yarn is used for the warp, and undyed or white yarn istypically used for the weft yarn. In some denim fabrics, the weft yarncan be dyed and have a color other than white, such as red. In the denimweave, the weft passes under two or more warp threads. FIG. 3 shows aweave with the weft passing under two warp threads. Specifically, thefabric weave is known as a 2×1 right-hand twill. For a right-hand twill,a direction of the diagonal is from a lower left to an upper right. Fora left-hand twill, a direction of the diagonal is from a lower right toan upper left. But in other denim weaves, the weft can pass under adifferent number of warp threads, such as 3, 4, 5, 6, 7, 8, or more. Inother implementation, the denim is a 3×1 right-hand twill, which meansthe weft passes under three warp threads.

Because of the weave, one side of the fabric exposes more of the warpyarns (e.g., warp-faced side), while the other side exposes more of theweft yarns (e.g., weft-faced side). When the warp yarns are blue andweft yarns are white, a result of the weave is the warp-faced side willappear mostly blue while the reverse side, weft-faced side, will appearmostly white.

In denim, the warp is typically 100 percent cotton. But some warp yarnscan be a blend with, for example, elastane to allow for warp stretch.And some yarns for other fabrics may contain other fibers, such aspolyester or elastane as examples.

In an indigo ring-dyed yarn, the indigo does not fully penetrate to acore of the yarn. Rather, the indigo dye is applied at a surface of thecotton yarn and diffuses toward the interior of the yarn. So when theyarn is viewed cross-sectionally, the indigo dyed material will appearas a ring on around an outer edge of the yarn. The shading of the indigodye will generally lighten in a gradient as a distance increases fromthe surface of the yarn to the center (or core) of the yarn.

During laser finishing, the laser removes a selected amount of thesurface of the indigo dyed yarn (e.g., blue color) to reveal a lightercolor (e.g., white color) of the inner core of the ring-dyed yarn. Themore of the indigo dyed material that is removed, the lighter the color(e.g., lighter shade of blue). The more of the indigo dyed material thatremains, the darker the color (e.g., deeper shade of blue). The lasercan be controlled precisely to remove a desired amount of material toachieve a desired shade of blue in a desired place or position on thematerial.

With laser finishing, a finish can be applied (e.g., printed or burnedvia the laser) onto apparel (e.g., jeans and denim garments) that willappear similar to or indistinguishable from a finish obtained usingtraditional processing techniques (e.g., dry abrasion, wet processing,and oxidation). Laser finishing of apparel is less costly and is fasterthan traditional finishing techniques and also has reduced environmentalimpact (e.g., eliminating the use of harsh chemical agents and reducingwaste).

FIGS. 4-7 show how the laser alters the color of ring-dyed yarn. FIG. 4shows a laser beam 407 striking a ring-dyed yarn 413 having indigo-dyedfibers 418 and white core fibers 422. The laser removes the dyed fibers,which can be by vaporizing or otherwise destroying the cotton fiber viaheat or high temperature that the laser beam causes.

FIG. 5 shows the laser using a first power level setting or firstexposure time setting, or a combination of these, to remove some of thedyed fibers, but not revealing any of the white core fibers. The undyedfibers remain covered. There is no color change.

FIG. 6 shows the laser using a second power level setting or secondexposure time setting, or a combination of these, to remove more of thedyed fibers than in FIG. 5 . The second power level is greater than thefirst power level, or the second exposure time setting is greater thanthe first exposure time setting, or a combination of these. The resultis some of the undyed fibers are revealed. There is a color change,subtle highlighting.

FIG. 7 shows the laser using a third power level setting or thirdexposure time setting, or a combination of these, to remove even more ofthe dyed fibers than in FIG. 6 . The third power level is greater thanthe second power level, or the third exposure time setting is greaterthan the second exposure time setting, or a combination of these. Theresult is more of the undyed fibers are revealed. There is a colorchange, brighter highlighting.

As shown in FIG. 2 , before laser 207, the fabric can be prepared 216for the laser, which may be referred to as a base preparation, and caninclude a prelaser wash. This step helps improves the results of thelaser. After the laser, there can be a postlaser wash 219. This wash canclean or remove any residue caused by the laser, such as removing anycharring (which would appear as brown or slightly burning). There can beadditional finish 221, which may be including tinting, softening, orfixing, to complete finishing.

FIG. 8 shows a technique where finishing 124 is divided into twofinishing steps, finishing I and finishing II. Finishing I 808 is aninitial finishing to create base templates 811. With finishing II 814,each base template can be used to manufacture multiple final finishes817.

FIG. 9 shows multiple base templates, base A, base B, and base C. Thesebase templates may be referred to as base fit fabrics or BFFs. In animplementation, the base templates can be created during base prep andprelaser wash 216 (see FIG. 2 ). During finishing I, by using differentwash 216 methods or recipes, each different base template can becreated.

Finishing II can include laser finishing. Base A is lasered withdifferent designs to obtain various final product based on base A (e.g.,FP(A)1 to FP(A)i, where i is an integer). Base B is lasered withdifferent designs to obtain various final products based on base B(e.g., FP(B)1 to FP(B)j, where j is an integer). Base C is lasered withdifferent designs to obtain various final products based on base C(e.g., FP(C)1 to FP(C)k, where k is an integer). Each base can be usedto obtain a number of different final designs. For example, the integersi, j, and k can have different values.

As described above and shown in FIG. 2 , after finishing II, there canbe additional finishing during post laser wash 219 and additionalfinishing 221. For example, during the postlaser wash, there may beadditional tinting to the lasered garments. This tinting can result inan overall color cast to change the look of the garment.

In an implementation, laser finishing is used to create many differentfinishes (each a different product) easily and quickly from the samefabric template or BFF or “blank.” For each fabric, there will be anumber of base fit fabrics. These base fit fabrics are lasered toproduce many different finishes, each being a different product for aproduct line. Laser finishing allows greater efficiency because by usingfabric templates (or base fit fabrics), a single fabric or material canbe used to create many different products for a product line, more thanis possible with traditional processing. This reduces the inventory ofdifferent fabric and finish raw materials.

For a particular product (e.g., 511 product), there can be two differentfabrics, such as base B and base C of FIG. 9 . The fabrics can be partof a fabric tool kit. For base B, there are multiple base fit fabrics,FP(B)1, FP(B)2, and so forth. Using laser finishing, a base fit fabric(e.g., FP(B)1) can be used to product any number of different finishes(e.g., eight different finishes), each of which would be considered adifferent product model.

For example, FP(B)1 can be laser finished using different laser files(e.g., laser file 1, laser file 2, laser file 3, or others) or havedifferent postlaser wash (e.g., postlaser wash recipe 1, postlaser washrecipe 2, postlaser wash recipe 3, or others), or any combination ofthese. A first product would be base fit fabric FP(B)1 lasered usinglaser file 1 and washed using postlaser wash recipe 1. A second productwould be base fit fabric FP(B)1 lasered using laser file 2 and washedusing postlaser wash recipe 1. A third product would be base fit fabricFP(B)1 lasered using laser file 2 and washed using postlaser wash recipe2. And there can be many more products based on the same base fitfabric. Each can have a different product identifier or uniqueidentifier, such as a different PC9 or nine-digit product code.

With laser finishing, many products or PC9s are produced for each basefit fabric or blank. Compared to traditional processing, this is asignificant improvement in providing greater numbers of differentproducts with less different fabrics and finishes (each of which intraditional processing consume resources, increasing cost, and taketime). Inventory is reduced. The technique of providing base fitfinishes or fabric templates for laser finishing has significant andmany benefits.

A system incorporating laser finishing can include a computer to controlor monitor operation, or both. FIG. 10 shows an example of a computerthat is component of a laser finishing system. The computer may be aseparate unit that is connected to a system, or may be embedded inelectronics of the system. In an embodiment, the invention includessoftware that executes on a computer workstation system or server, suchas shown in FIG. 10 .

FIG. 10 is a simplified block diagram of a distributed computer network1000 incorporating an embodiment of the present invention. Computernetwork 1000 includes a number of client systems 1013, 1016, and 1019,and a server system 1022 coupled to a communication network 1024 via aplurality of communication links 1028. Communication network 1024provides a mechanism for allowing the various components of distributednetwork 1000 to communicate and exchange information with each other.

Communication network 1024 may itself be comprised of manyinterconnected computer systems and communication links. Communicationlinks 1028 may be hardwire links, optical links, satellite or otherwireless communications links, wave propagation links, or any othermechanisms for communication of information. Communication links 1028may be DSL, Cable, Ethernet or other hardwire links, passive or activeoptical links, 3G, 3.5G, 4G and other mobility, satellite or otherwireless communications links, wave propagation links, or any othermechanisms for communication of information.

Various communication protocols may be used to facilitate communicationbetween the various systems shown in FIG. 10 . These communicationprotocols may include VLAN, MPLS, TCP/IP, Tunneling, HTTP protocols,wireless application protocol (WAP), vendor-specific protocols,customized protocols, and others. While in one embodiment, communicationnetwork 1024 is the Internet, in other embodiments, communicationnetwork 1024 may be any suitable communication network including a localarea network (LAN), a wide area network (WAN), a wireless network, anintranet, a private network, a public network, a switched network, andcombinations of these, and the like.

Distributed computer network 1000 in FIG. 10 is merely illustrative ofan embodiment incorporating the present invention and does not limit thescope of the invention as recited in the claims. One of ordinary skillin the art would recognize other variations, modifications, andalternatives. For example, more than one server system 1022 may beconnected to communication network 1024. As another example, a number ofclient systems 1013, 1016, and 1019 may be coupled to communicationnetwork 1024 via an access provider (not shown) or via some other serversystem.

Client systems 1013, 1016, and 1019 typically request information from aserver system which provides the information. For this reason, serversystems typically have more computing and storage capacity than clientsystems. However, a particular computer system may act as both as aclient or a server depending on whether the computer system isrequesting or providing information. Additionally, although aspects ofthe invention have been described using a client-server environment, itshould be apparent that the invention may also be embodied in astand-alone computer system.

Server 1022 is responsible for receiving information requests fromclient systems 1013, 1016, and 1019, performing processing required tosatisfy the requests, and for forwarding the results corresponding tothe requests back to the requesting client system. The processingrequired to satisfy the request may be performed by server system 1022or may alternatively be delegated to other servers connected tocommunication network 1024.

Client systems 1013, 1016, and 1019 enable users to access and queryinformation stored by server system 1022. In a specific embodiment, theclient systems can run as a standalone application such as a desktopapplication or mobile smartphone or tablet application. In anotherembodiment, a “Web browser” application executing on a client systemenables users to select, access, retrieve, or query information storedby server system 1022. Examples of Web browsers include the InternetExplorer browser program provided by Microsoft Corporation, Firefoxbrowser provided by Mozilla, Chrome browser provided by Google, Safaribrowser provided by Apple, and others.

In a client-server environment, some resources (e.g., files, music,video, or data) are stored at the client while others are stored ordelivered from elsewhere in the network, such as a server, andaccessible via the network (e.g., the Internet). Therefore, the user'sdata can be stored in the network or “cloud.” For example, the user canwork on documents on a client device that are stored remotely on thecloud (e.g., server). Data on the client device can be synchronized withthe cloud.

FIG. 16 shows a block diagram of a system for creating, designing,producing apparel products with laser finishing. A box line plan 1602 isan internal and interim tool for communication between a merchandisinggroup and design group. Through the box line plan, merchandising cancommunicate what needs to be designed by the design group. The box lineplan can have open slots to be designed 1609.

There is a digital design tool 1616 merchants and design can use toclick and drag finish effects (e.g., laser files) and tint casts overimages of base washes in order to visualize possible combinations andbuild the line visually before the garment finish is actually finishedby the laser. The visualizations can be by rendering on a computersystem, such as using three-dimensional (3D) graphics.

U.S. patent application 62/433,746, filed Dec. 13, 2016, which isincorporated by reference, describes a system and operating model ofapparel manufacture with laser finishing. Laser finishing of apparelproducts allows an operating model that reduces finishing cost, lowerscarrying costs, increases productivity, shortens time to market, be morereactive to trends, reduce product constraints, reduces lost sales anddilution, and more. Improved aspects include design, development,planning, merchandising, selling, making, and delivering. The model usesfabric templates, each of which can be used be produce a multitude oflaser finishes. Operational efficiency is improved.

Designers can use the digital design tool to design products that areused to satisfy the requests in open slots 1609. Designs created usingthe digital design tool can be stored in a digital library 1622. Inputto the digital design tool include fabric templates or blanks 1627(e.g., base fit fabrics or BFFs), existing finishes 1633 (e.g., can befurther modified by the tool 1616), and new finishes 1638. New finishescan be from designs 1641 (e.g., vintage design) captured using a laserfinish software tool 1645, examples of which are described in U.S.patent applications 62/377,447, filed Aug. 19, 2016, and Ser. No.15/682,507, filed Aug. 21, 2017. Digital library 1622 can be accessibleby the region assorting and sell-in 1650. And the digital library can beused populate or satisfy the box line plan.

FIG. 17 shows a block diagram of a specific implementation of a digitaldesign tool, a preview tool 1703. Digital design tool 1616 can berepresentative of a collection of tools, such as an application suite,including desktop or mobile apps, or a combination.

Preview tool 1703 can be a single tool in a toolbox or toolkit used forlaser finishing of garments, or the tool can be incorporated as afeature of another tool. The preview tool allows a user such as aclothing designer to preview on a computer screen or to generate adigital representation (e.g., image file, JPEG file, BMP file, TIFFfile, GIF file, PNG file, PSD file, or others) of jeans in a selectedbase fit fabric or fabric template 1706 with a selected laser pattern1709 (e.g., from a laser input file). With the digital representation,the user will be able to see or preview the jeans in the selected basefit fabric as if it had been burned with the selected laser input file,without needing to actually laser or burn the jeans.

Some files are described as being of an image file type. Some examplesof image file types or file formats include bitmap or raster graphicsformats including IMG, TIFF, EXIF, JPEG, GIF, PNG, PBM, PGM, PPM, BMP,and RAW. The compression for the file can be lossless (e.g., TIFF) orlossy (e.g., JPEG). Other image file types or file formats includevector graphics including DXF, SVG, and the like.

Bitmaps or raster graphics are resolution dependent while vectorgraphics are resolution independent. Raster graphics generally cannotscale up to an arbitrary resolution without loss of apparent quality.This property contrasts with the capabilities of vector graphics, whichgenerally easily scale up to the quality of the device rendering them.

A raster graphics image is a dot matrix data structure representing agenerally rectangular grid of pixels, or points of color, viewable via amonitor, paper, or other display medium. A bitmap, such as a single-bitraster, corresponds bit-for-bit with an image displayed on a screen oroutput medium. A raster is characterized by the width and height of theimage in pixels and by the number of bits per pixel (or color depth,which determines the number of colors it can represent).

The BMP file format is an example of a bitmap. The BMP file format, alsoknown as bitmap image file or device independent bitmap (DIB) fileformat or simply a bitmap, is a raster graphics image file format usedto store bitmap digital images, independently of the display device. TheBMP file format is capable of storing two-dimensional digital images ofarbitrary width, height, and resolution, both monochrome and color, invarious color depths, and optionally with data compression, alphachannels, and color profiles.

The fabric template can be selected from a library of fabric templateimages 1716 or may be a new image uploaded or provided by the user. Eachfabric template images is an image file of a jeans in a base fit fabricor other material. For each jeans model or fit (e.g., models or fits311, 501, 505, 511, 515, 541, 569, 721, and others), there would be oneimage in each different material or base fit fabric.

The laser input file can be selected from a library of laser input files1722 (e.g., files created from vintage jeans or from a group ofdesigners), may be a file 1718 created by the user, or may be a fileuploaded or provided by the user. For example, the user may have createdthe laser pattern (contained within a laser input file) manually using agraphical or image editing tool (e.g., Adobe Photoshop and similar photoediting programs). Or the laser pattern may have been created byanother, such as selected from a library of laser files. The laserpattern may be generated by a computer or automated process, such as maybe used to obtain a laser pattern from vintage jeans. The user will beable to see the results of a burn, make any manual changes oralterations to the pattern (such as additional changes to a vintage jeanpattern in a digital image file) and preview the results again. Thepreview tool allows a user to make and see changes, to the user canobtain feedback faster than having to laser jeans to see the results andalso avoiding unneeded waste (e.g., preliminary versions of burnedjeans).

Each digital representation can be saved in a separate images, and agroup or set of the images can be a called brief of collection of jeans.The preview tool can be used for merchandising, such as generatingimages of a proposed line of products for a particular season, and theseimages can be shared among members of a team to discuss any additions,changes, or deletions to a collection.

A specific version of the preview tool overlays a fabric template inputfile and a laser input file, and then generates an image to display themtogether as a representation of the laser-finished apparel. The laserinput file is aligned to the garment in the fabric template input file,so that the positioning of features in the laser input file and atappropriate positions or places on the garment. The alignment may be byusing alignment marks that are in the input files. The alignment may bean automated alignment or scaling, or a combination.

Brightness, intensity, opacity, blending, transparency, or otheradjustable parameters for an image layer, or any combination of these,are selected or adjusted for the laser input file, so that when thelaser input file is overlaid above the fabric template image, the lookof the garment will appear of simulate the look of a garment had beenburned by a laser using that laser input file.

Adjustable parameters such as opacity can be used to blend two or moreimage layers together. For example, a layer's overall opacity determinesto what degree it obscures or reveals the layer beneath it. For example,a layer with 1 percent opacity appears nearly transparent, while onewith 100 percent opacity appears completely opaque.

Further, a dots per inch (dpi) of the combined image can be adjusted toalso more properly simulate the look of a garment more closely with aburned garment. Dots per inch refers to the number of dots in a printedinch. The more dots, the higher the quality of the print (e.g., moresharpness and detail). By reducing the dpi of the image, this willreduce the image quality, resulting a blurring of the image. In animplementation, the preview tool reduces a dpi of the combined image, tobe of less dpi than the fabric template input file or the laser inputfile. By blurring the preview image, this results in improved simulationthat corresponds better to a burned laser garment. When burning agarment, the garment material or fabric typically limits the resolutionof the result to less than that of the input file.

In an implementation, the dpi of the laser input file is about 72 dpi,while the dpi of the preview image is about 34 dpi. In animplementation, the dpi of the fabric template input file and laserinput file are about 36 dpi or above, while the dpi of the preview imageis about 36 dpi or lower.

FIG. 18 shows a block diagram of a digital brief tool 1803, which alsolike preview tool 1703, provides a real-time preview of an appearance ofpair of jeans when a finishing pattern is applied by burning using alaser input file. The digital brief tool has additional features toallow more flexible designing of jeans.

It should be understood that the invention is not limited to thespecific flows and steps presented. A flow of the invention may haveadditional steps (not necessarily described in this patent), differentsteps which replace some of the steps presented, fewer steps or a subsetof the steps presented, or steps in a different order than presented, orany combination of these. Further, the steps in other implementations ofthe invention may not be exactly the same as the steps presented and maybe modified or altered as appropriate for a particular application orbased on the data or situation.

The digital brief tool takes as input three types of digital assets1805, fabric template input 1816, damage input 1819, and laser inputfile 1822. Fabric template input 1816 and laser input file 1822 aresimilar to the inputs for the preview tool. Damage input 1819 is animage of damage (e.g., holes, rips, shredded regions, or openings ofvarious shapes and sizes) that can be burned by a laser into jeans. Thedigital brief tool overlays the damage and laser input files over thefabric template.

The user selects a fabric template input, which an image of a jeansstyle in a particular base fit fabric. The user can optionally selectone or more damage inputs. If a damage input is selected, the damageinput will be a layer that overlays the fabric template layer. As forthe preview tool, the user selects a laser input file with laser patternand overlays the fabric template layer. As the user selects the inputs,the user will be able to see in real time the inputs and any changes orupdates in a preview image or brief.

After the inputs are selected, the user can select and perform one ormore operations 1826 on the inputs using the digital brief tool. Theseoperations including adding tint 1831, adjusting intensity 1834,adjusting bright point 1837, move digital asset 1842, rotate digitalasset 1845, scale digital asset 1848, and warp digital asset 1852. Asthe user selects and performs one or more operations, the user will beable to see in real time the changes or updates in the preview image orbrief.

After the fabric template input, the user can add tinting 1831. Tintingwill adjust the hue of the color of the fabric template input. Tintingis representative of the tinting which can be added during the postlaserwash or finishing II, described above. The user will be able to select atint color, and this tint color will be blended with the existing colorof the fabric template input. The amount or intensity of the tinting canbe increased or decreased, such as by using a slider bar.

The user can adjust intensity 1834. In an implementation, intensityadjusts a weight matrix by a percentage of each value in the array. Inan implementation, intensity (or brightness) adjusts an opacity of agenerated adjustment layer (see hue saturation lightness adjustmentlayer described below). The greater the opacity, the more opaque thislayer will appear in the preview or brief image. The less the opacity,the less opaque this layer will appear in the preview or brief image;the layer will appear more transparent so that the layer beneath willshow through more.

When increasing brightness, the opacity of the adjustment layerincreases, and since the adjustment layer is above the fabric templateinput, the generated adjustment layer will become more prominent orvisible, thus making this layer (which has the finishing pattern)brighter. Similarly, when decreasing brightness, the opacity of theadjustment layer decreases, the generated adjustment layer will becomeless prominent or visible, thus making this layer (which has thefinishing pattern) less bright or fainter. The amount of the intensitycan be increased or decreased, such as by using a slider bar.

The user can adjust bright point 1837. Bright point adjusts the effectof the laser input file on the fabric template input. In animplementation, bright point adjustment changes a midpoint of agrayscale, creating a piecewise linear mapping of the pattern file.

Increasing the bright point will increase an effect of the laser pattern(e.g., causing greater laser pattern highlights) in the laser input fileon the fabric template input, while decreasing the bright point does theopposite (e.g., diminishing laser pattern highlights). The bright pointadjustment can be analogous to changing a pixel time or the time thatthe laser stays at a particular position for a given input from thelaser input file. The amount of the bright point can be increased ordecreased, such as by using a slider bar.

The user can move 1842 or reposition a selected digital asset. Forexample, a damage input (or fabric template or laser file) may be movedto a position desired by the user. The user can rotate 1845 a selecteddigital asset. For example, a damage input (or fabric template or laserfile) may be rotated to any angle relative to the other layers asdesired by the user.

The user can scale 1848 a selected digital asset. This scaling can belocked, maintaining the original aspect ratio of the digital asset, orcan be unlocked, such that the user can change the aspect ratio. Theuser can warp 1852 a selected digital asset. With warping, the user canadjust an aspect ratio of a portion of the digital asset differentlyfrom another portion. For example, one portion of a damage input (orfabric template or laser file) can be squished (e.g., right and leftedges of image pushed toward each other) while another portion isexpanded (e.g., right and left edges of image pulled away from eachother).

After the user has performed selected operations 1826, the digital brieftool shows an image of the jeans with the laser finishing pattern,including any tinting, damage, or other adjustments, as created by theuser. This image can be saved and viewed again later. A user can createmultiple designs, and these can be saved together as part of acollection.

FIG. 19 shows a technique of generating a preview of a finished imageusing a digital brief tool. A base image (or fabric template input) isselected. A hue saturation lightness (HSL) adjustment layer is createdor generated for the selected base image. The HSL adjustment layer canbe the base layer with an adjustment for hue saturation lightness. Whentinting is selected, a solid color adjustment layer is created orgenerated. The solid color adjustment layer has a solid color (e.g.,yellow, green, red, blue, or other color that is used for tinting thegarment) that is in the same form or outline as the garment (e.g.,pants), as indicated by the dotted lines in the figure.

To obtain a final result, which is the final image of the jeans withlaser finishing pattern, a laser pattern mask is combined with the baseimage and HSL adjustment layer. A resulting combination will be based onintensity and bright point settings.

The laser pattern mask is a negative image or reverse image of the laserinput file. For the laser input file, during laser burning, a whitepixel means the pixel is not lasered (which results in the originalindigo color of the fabric), and a black pixel means the pixel will belasered at highest level (which results in the whitest color that can beachieved on the fabric). In an implementation, the laser input file has256 levels of gray, and for levels between 0 (e.g., black) and 255(e.g., white), then the amount of laser burning will be proportionallysomewhere in between.

FIG. 20 shows a block diagram of a technique of generating a preview ofa laser finishing pattern on a garment, such as jeans. The technique maybe embodied in a preview generation tool 2001. Inputs to a createpreview image process 2002 include a base template image 2007 and laserinput file 2009. The base template image is used to create an adjustedbase template image 2017, which is also input to the create previewimage process. These create preview image process uses these threeinputs to create a preview image 2027, which can be displayed on acomputer screen for the user.

The adjusted base template image is created from the base template imageby adjusting its hue, saturation, or lightness, or any combination ofthese. Compared to the original base template image, the adjusted basetemplate image will appear washed out or bleached. In other words, theadjusted base template image will appear as if the garment in the basetemplate image were fully bleached or lasered. The adjusted basetemplate image can be an HLS adjustment layer as discussed above.

Digital Brief Tool

Embodiments of a digital brief tool (or garment preview tool) mayexecute on Apple Inc.'s iPad Pro tablet computer device. Although thescreens portray the digital brief tool as executing on an iPad Pro,other suitable electronic devices may execute the digital brief tool.For example, the digital brief tool may execute on a Windows device(e.g., Windows 10 tablet), an Android device, other iPad product familymodels (e.g., iPad or iPad mini), or many other devices.

The iPad Pro 12.9 is a tablet device with rectangular dimensions of 12inches by 8.68 inch, and is 0.27 inches thick. The iPad Pro has a12.9-inch screen, and has nonvolatile memory storage of 64, 256, or 512gigabytes. The iPad Pro has network connectivity via Wi-Fi andoptionally cellular. The iPad Pro has an A10X Fusion chip with 64-bitarchitecture and an embedded M10 coprocessor. Some features of thedigital brief tool can be accelerated by using specialized featuresavailable in the A10X Fusion chip or embedded M10 coprocessor, or both.An operating system of the iPad Pro is Apple iOS 11 (or greater whenreleased). Further, the iPad Pro can be operated with a stylus, theApple Pencil product. And in an implementation, the use can use theApple Pencil with the digital brief tool.

The digital brief tool includes various features, allowing a designer toselect, create, and visualize how an apparel item will look with certaincharacteristics, before the apparel item is produced. The digital brieftool may allow the designer, for one or more characteristics of aproposed apparel item, to assign one or more options to each of thecharacteristics. While assigning the options for characteristics, thedigital brief tool allows the designer to see, based on currentlyassigned options, how the apparel item may appear when produced, in realtime as changes are made.

Selecting gender, series, fit, fabric, or other characteristics in thedigital brief tool may result in having only relevant options presentedto the designer. For example, some characteristics or options may bespecific to a particular gender. Upon selection of the particulargender, characteristics and options with the selected gender will appearfor the designer to use for a proposed apparel item.

In an implementation, the digital brief tool is adapted for use withproducing jeans. For example, the following figures may include variouscharacteristics and options relevant to designing and stylizing ofjeans. However, the digital brief tool may be adapted for use with otherapparel items, such as shirts, jackets, pants, or socks.

Some specific implementations of a digital brief tool are discussed inU.S. application Ser. Nos. 16/177,387, 16/177,412, and 16/177,407, filedOct. 31, 2018, which are incorporated by reference.

Apparel Management System

FIG. 21 shows a system for apparel manufacturing and sales, where theapparel can include garments that have been finished using laserfinishing. There is an apparel management system 2122, which controlsoperation of the system. The apparel management system is connected by anetwork 2124 to components of the system, including sales and ordering2126, manufacturing 2128, and distribution and delivery 2130 components.The network can be a computer network, such as the Internet.

Using the sales and order component, a customer can preview and selectsgarments to order. The customer can be a buyer for a retail store,internal buyer for retail sales of a region, regional salesperson, orother customer. The sales process can include using a variety of toolsto assist a customer with showing available products, selecting productsto purchase, keeping an order within budget, accessing a history ofprevious orders, and customizing and selecting fits, styles, and sizesof products. As an example, the customer can view products and order viaa digital showroom. The products are shown digitally, which reduces theamount of physical samples that need to be produced. Further, thecustomer can also order via a Web site managed by the apparel managementsystem. After the customer completes the order, the order is sent viathe network (e.g., Internet) to the apparel management system.

The apparel management system sends the order to the manufacturingcomponent, where the order is made. Manufacturing can include cuttingthe fabric material, assembling or sewing together the cut panels, andfinishing the apparel item using a laser. An apparel manufacturer canhave numerous manufacturing centers, and the apparel management systemwill send the order to a manufacturing center that is appropriate forthe customer and order. The determination is based on a location of thecustomer (e.g., shipping time to customer from manufacturing center) andthe apparel item selected (e.g., availability of material). The systemensures the order will be fulfilled efficiently in short amount of time.

In an implementation, the laser finishing is done after the garment isassembled. Specifically, the material is cut, assembled into a garment,and then the garment is finished using a laser. The finishing is basedon style or customization selected by the customer in the order.

In another implementation, the laser finishing is before the garment isassembled. Specifically, before the material is cut, fabric rolls orsheets of material are finished using the laser. The finishing is basedon style or customization selected by the customer in the order. Thenthe material is cut into panels, and the panels are assembled into thegarment.

After manufacture of the garments of the order is complete, the apparelmanagement system controls distribution, shipping, and delivering of theordered garments to the customer. The apparel management system can sendthe customer tracking information for the order so that the customer cantrack the order.

Depending on various factors which may delay manufacture of some items,an order with multiple items may be sent to the customer in multiplepartial shipments rather than a single complete shipment. The items notshipped at the same time will be shipped later when available. Theapparel management system handles communicating with the customerregarding delays and provides an estimate of when the customer canexpect to receive the items of the order.

Digital Showroom Tool

FIG. 22 shows block diagram of a digital showroom system, which can bepart of the sales and ordering component 2126 of the apparelmanufacturing and sales system. A digital showroom 2208 is a salesshowroom where customers can visit and see apparel products, selectproducts, and then enter orders. The digital showroom can include largedisplay panels or projectors for customers to view, one or more tabletdevices, user input devices (e.g., keyboard, mouse, pointer, touchscreen, or touch panel), physical displays (e.g., mannequins, models,sample base fabric templates, and other samples), and one or moreprojectors for use with the physical displays.

The digital showroom 2208 is connected via a network 2216 to a digitalshowroom computing system 2223, which controls operation of the devicesand tools available in the digital showroom. The network can be acomputer network. The digital showroom computing system has access to aproduct info database (e.g., product lifecycle management (PLM)database), base templates, and laser input files. Previews of garmentproducts can be shown on the display panels, tablet, or on the physicaldisplays, or any combination of these.

Order Tool

FIG. 23 shows an order tool 2301, which can be tool that is part of thedigital showroom system. Using the order tool, the customer can order agarment for manufacture and delivery. The order tool allows the customerto select a design, preview the design, and order the design. Thecustomer can select a preset design, make a custom design, or makesemicustom design. A semicustom design is a design based on a previousdesign, such as a preset design or a previously saved design, which ismodified to obtain a new design. The tool also allows the customerupload a design or portion or a design to be manufacture. For example,an image can be captured by a camera, which is then uploaded via theorder tool. The order tool allows selection of sizing.

Surface Projection

FIGS. 24-29 describe a projector preview tool. The projector previewtool allows a user to design garments, such as using the digital brieftool, and see the designed garment projected onto a surface in reallife. The surface does not need to be flat. In fact, the projector toolmay use a mannequin of a person or a part of a person, to project withlight onto the surface of the mannequin. This gives the user a good ideaof how the apparel may appear in the real world, without manufacturingthe garment. This tool can be used to project a wear or other finishingpattern (e.g., from a laser input file) onto a physical pair of jeans ina particular base fabric template being worn by a mannequin, person, orother physical object. Then the user will be able to physically see whatthe jeans will look like after laser finishing.

To allow a preview of a product preview, the user or viewer is able toproject a selected finishing pattern (e.g., laser input file) onto agarment (e.g., base fabric template) in the room. In order to maintain arealistic image preview the image is altered (e.g., warped or distorted)such that it will show up correctly when projected on a nonflat surface.In addition the image will be reinverted to show high intensities asbrighter. This is because the laser input file is a negative image,where dark pixels will result in the bright points on lasered jeans.Once the image can be projected, an image sensor will help determine theaccuracy of the preview and optimize the brightness values beingprojected if needed. The image sensor is an optional feature, and may beomitted if additional feedback and enhancement of the projected resultsare not desired.

FIG. 24 shows a system diagram for a system including the projectorpreview tool 2401. The tool is coupled to a projector 2405 that projectslight onto a mannequin 2407. The tool is also coupled to a sensor 2408that is capturing images of the mannequin 2407, such as when theprojector 2405 is projecting onto the mannequin 2407. The tool includesa sensor feedback and updates features. The sensor feedback featurereceives images from the sensor 2408. The update feature processesimages and determines how, based on the images, whether or not theprojector 2405 should modify the projected image.

FIG. 25 shows a flow diagram for a system including the projectorpreview tool. In a step 2501, the system includes providing a garmentpreviewing tool. The garment previewing tool may be the digital brieftool, as described elsewhere in this application. The digital brief mayprovide various options for a user, such as providing options for theuser to select a base garment image. For example, the base garment imagemay be a jeans base garment. The base garment image may be composed ofany material suitable for laser finishing. The user may also select afinishing pattern, associated with a laser pattern file that may beprocessed to create the finishing pattern onto a target garmentcorresponding to the base garment image. The user may also modify theposition, the sizing, or a combination, of the finishing pattern. Forexample, as the base garment image is shown, the user may modify theposition, the sizing, or the combination, of the finishing pattern. Inresponse to, or in near real-time, the system may show to the user themodifications, without needing to first manufacture the target garment.Using the garment previewing tool, the user may also add a garmentfeature and modify the sizing or positioning of the garment feature.Some garment features included with the garment previewing tool includesa label, fastener, buckle, embellishment, embroidery, grommet, heattransfer pattern, lace, patch, printing, foil, ribbon, tab, foil, rivet,sequin, pocket, thread, or zipper.

In a step 2505, the system includes applying a distortion to a garmentpreview image. The garment preview image may be a garment preview imageof a jeans base image and selected finishing pattern, with modifiedsizing or modified positioning, or a combination, generated with thegarment previewing tool. The distortion may approximate how the jeansbase image and selected finishing pattern, with modified sizing ormodified positioning, or a combination, needs to be modified to appearon a three-dimensional mannequin. The 3D mannequin may be an incompletebody, such as just the legs, top, torso, or any combination of these.For example, the lights will mimic how the garment preview image willappear, when modified to adapt to the contours and shape of the 3Dmannequin.

In an implementation, before projecting, the system may use a structuredlight technique to determine contours of the three-dimensionalmannequin. For example, the structured light may include a known lightpattern. By shining the known light pattern onto the 3D mannequin, thesystem determines how the light pattern is appearing and can determinethe contours of the 3D mannequin.

In a step 2510, the system includes projecting the garment preview imageand capturing an image. For example, the garment preview image, asprojected onto the 3D mannequin, is captured using a camera.

In a step 2515, the system includes refining the distorted garmentpreview image. For example, the system may determine whether the resultsof the garment preview image on the 3D mannequin, based on the capturedimage, is within a tolerance of how the garment preview image shouldappear. As a example, the system determines whether the preview image isproperly projected as either too large (so that the garment previewimage extends past edges of the 3D mannequin), too small (so that thegarment preview image does not extend to edges of the 3D mannequin),improperly centered, does not match a contour of the three-dimensionalmannequin, warp, brightness level, color balance, saturation level, hue,or any combination of these. The step of projecting the garment previewimage and capturing the image may be repeated. For example, as updatesare made to the distorted garment preview image, the system maycalculate a difference ratio of the distorted garment preview image tohow it should appear. If the difference ratio is greater than athreshold, steps 2505, 2510, and 2515 may be repeated.

In a step 2520, the system includes providing a target garment andcreating a finishing pattern on the target garment. The target garmentincludes a real-world version of the base garment selected by the user.For example, the target garment is a pair of jeans, adapted for laserfinishing. From the input with modified sizing or positioning from theuser, the target garment is finished with the finishing pattern. Thetarget garment may be created using the garment preview image identifiedabove. The garment preview image may be generated before creating thefinishing pattern on the target garment.

FIG. 26 shows a projector 2601 used to project a finishing pattern ontojeans. The projector takes as input a laser input file with finishingpattern. The jeans are placed on a mannequin or model 2605. Differentmannequins may be used by the projector preview tool for differentpurposes. There may be different mannequins for different sizes andshapes of garments. For example, different mannequins may be used forgarments that are meant to be looser or baggier or for different fittypes (e.g., skinny, straight, athletic).

In an implementation, the tool uses a structured light technique tocalibrate a projector. In this technique, a known pattern is projectedonto a mannequin. The results of the projection are captured by thecamera. Because the pattern of light being projected is known, a warpingof the projected pattern around the mannequin can be used to calculatesize and shape of the mannequin. Based on the results of thecalculation, initial measurements for how to warp a garment image toappear are made.

Since the jeans are being worn, there will be surface contours and thejeans will not be flat. And the jeans may be angled with respect to theprojector lens. However, the laser input file is for jeans when flat,not worn. This is because the jeans will be lasered while flat. In orderto project the laser input file correctly onto the worn jeans, amathematical transformation is performed. This transformation alters(e.g., warps or distorts) the image file. This results in an accurateprojector preview of the worn jeans with laser finish pattern.

There can also be a sensor 2603 which receives feedback on the projectedimage, and makes adjustments or corrections to make the projected imagemore accurate. For example, the jeans may be worn by a model who walksacross the room or to different locations in the room, and the projectorand sensor will work together to make changes so that the finishingpattern will be accurately displayed on the jeans.

FIG. 27 shows flow for a projector preview tool. As inputs, there are afinish or finishing pattern (e.g., laser input file) and a garment(e.g., base fabric template) on a mannequin or model. For the garment onmannequin, we determine a projection surface, surface profile, anddistance. These are input to an image distortion for projection onshaped surface process to generate an altered (e.g., warped ordistorted) image. The image is inverted to make high laser intensitiesbrighter. The inverted image is used as a projection image to projectthe pattern onto the mannequin.

There can also be a feedback loop for image optimization. An imagesensor gathers feedback data from the projected pattern. This feedbackdata is used to optimize the image. More detail is provided below inFIG. 29 .

FIG. 28 shows of a technique of shape projection. With a 3D mapping ofthe finish pattern, multiple views can be produced through rotationsabout a specified axis. There is a matrix for rotation Z, rotation Y,and rotation X. There is a matrix for scaling in three dimensions. Thereis a matrix for translation in three dimensions. By matrix multiple,these matrices are used to calculated new X, Y, and Z coordinates at adesired rotation angle. As an example, a vector X, Y, Z is multiplied bythe rotation Z matrix to determine new X, Y, Z coordinates rotated bytheta degrees about Z.

In FIG. 28 , the variables are: θ=rotation angle about Z; β=rotationangle about Y; α=rotation angle about X; Sx=scale factor in X; Sy=scalefactor in Y; Sz=scale factor in Z; Tx=translation in X; Ty=translationin Y; Tz=translation in Z; X=current X position; Y=current Y position;and Z=current Z position.

FIG. 29 shows a feedback technique to optimize or enhance the accuracyof the projector preview. This may be represented as a feedback loop2901. For image from sensor, an image is taken of the projector previewoutput. For measure, the result will be scaled and overlaid to aninternal image for a comparison of what the projector should bedisplaying. For analyze, determine the corrections (e.g., pixel-basedbrightness adjustments) used to bring output closer to intended output.For correct, perform brightness corrections. For repeat, repeat untilprojector output is within tolerance of the intended image.
